INSULATOR.

SPECIFICATION forming part of Letters Patent No. 479,134, dated July 19, 1892. Application filed January 20, 1892. $erial No. 418,722. (No model.)

To all whom it may concern.-

Be it known that I, OHAUNcnY EUGENE OONOVER, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and useful Improvement in Insulators to be Used for Electrical Purposes, of which the following is a specification.

The object of my invention is to provide a novel and efficient insulator for electrical purposes; and it consists of the features of construction hereinafter described and claimed, reference being had to the accompanying drawings, in which Figure 1 represents a top view of an insulator embodying my improvement. Fig. 2 is a side elevation of the same. Figs. 3 and 4 are respectively a top view and side elevation of an insulator embodying my invention, but of a modified form from Figs. 1 and 2.

Similar figures of reference indicate corresponding parts in the several views.

In Figs. 1 and 2 the figure 1 represents the body of the insulator; 2 and 3, ears or projecting portions extending out from the body of the insulator; 4, a groove or seat for the line-wire; 5, the line-wire; 6, an annular groove for retaining a tie-wire; 7, a central hole for receiving a screw or a fastening device for securing the insulator in position; 8, a groove or opening between the ears 2 and 3 for the entrance to its seat of the line-wire.

In the modified form shown in Figs. 3 and 4, 1' represents the body of the insulator; 2 and 3, ears thereon; at, the line-wire groove or seat; 5, the line-wire; 7 7 holes by which it may be secured in position; 8, a groove between the ears 2 and 3.

The insulators are made, by preference, of glass or porcelain, but may be made of any other material suited for the purpose.

In Figs. 1 and 2 a central hole 7 furnishes means for securing the insulator upon a pole, cross-bar, or other object, and in Figs. 3 and 4 two holes 7' are provided for said purpose; but my invention is not restricted to any particular form of insulator or method of securing the same in position for use.

A groove or seat for the line-wire 4 or at is provided, over which groove ears are project ed, one upon each side of said line -wire groove. They are of triangular form with reference to the line-wire groove, one angle of which is extended over said groove nearly to or past the center thereof. Said angular extensions are not placed directly opposite each other, one being forward of the otherin a lateral direction or the direction of the linewire, whereby a groove or space is left be tween said ears in a direction diagonal with said line-wire groove. This diagonal groove is made a little larger or wider than the wire to be used with the insulator, whereby said Wire can be placed in the insulator by giving to the wire a slight bend in the direction of the groove between said ears without making a permanent bend to the wire, and also while the wire is drawn comparatively tight. The line-wire will, as soon as it is below said angular projection of the ears, assume its position in its groove or seat, while said angular projections, each one partially or wholly covering the wire, retain it therein. The wire can be quickly inserted or removed and re quires no other fastening for many purposes.

By means of the construction shown in Figs. 1 and 2 the advantages of the old or most generally used form of insulator, having the annular groove 6 for retaining the tiewire, are retained, with the additional advantage of the line-wire seat, thus taking the weight of the line-wire from the tie-wire, also obviating the use of a tie-wire on every insulator, and thereby effecting a great saving in the amount of tie-wire required, as well as a saving in the time used in tying the same upon the insulator.

Among the advantages claimed in the use of my improvement over some of the older inventions are that the line-wire can be pulled tight before placing it within the insulator and be put in while tight instead of threading it through a hole and pulling it tight afterward; also, that a secure seat is provided for the support of the line-wire regardless of any tying-wire.

The modification shown in Figs. 3 and t may be used in a horizontal or perpendicular position, as its location requires, it being adapted to retain the wire equally well in either position.

Having described my invention, what I claim, and desire to secure byLctters Patent, 1S

seat, and having, also, in the same plane therewith and encircling said main body a tie-wire groove, a straight groove arranged to diagonally with said line-wire groove or seat and leading thereto, and the ears 2 and 8, one at each end of said diagonal groove and above the line-wire groove or seat, for retaining the line-wire therein, substantially as described.
